In the war between parasite and host, the parasitic wasp, Aphidius ervi, and the pea aphid, Acyrthosiphon pisum, are locked in a battle for survival. New research published in BioMed Central's open access journal BMC Biologyshows that this cunning parasite sniffs out differences between protected and unprotected aphids, and alters its egg-laying strategy, in order to overwhelm aphid defenses and e

Neither births nor deaths stop the flocking of organisms. They just keep moving, says theoretical physicist John J. Toner of the University of Oregon. The notion, he says, has implications in biology and eventually could point to new cancer therapies. Picture any scenario in which self-propelled organisms -- animals, birds, bacteria, molecules within cells, cancer cells, fish, and even tiny plasti

By training birds to 'get rhythm', scientists uncover evidence that our capacity to move in time with music may be connected with our ability to learn speech. Even though typical dance-floor activity might suggest otherwise, humans generally demonstrate a remarkable capacity to synchronize their body movements in response to auditory stimuli. But is this ability to move in time to musical rhythm a

A green roof system is an extension of the existing roof which involves a high quality water proofing and root repellant system, a drainage system, filter cloth, a lightweight growing medium and plants. In North America, the benefits of green roof technologies are poorly understood and the market remains immature, despite the efforts of several industry leaders. In Europe however, these technolo

Plant and computer scientists can now study the underground world of plants with more accuracy and clarity. The revolutionary technique will improve our chances of breeding better crop varieties and increasing yields. Developed at The University of Nottingham by a team of experts from the Schools of Biosciences and Computer Science, the new approach is based on the same X-ray technology used in ho

Improving natural photosynthesis to make new fuels and boost crop production is the focus of Biotechnology and Biological Sciences Research Council (BBSRC) funded research presented at the American Association for the Advancement of Science (AAAS) Annual Meeting February 17. It could see us one step closer to bottling the sun's energy or turbocharging plants to produce bumper crops. Photosynthesi

Team from University of the Basque Country manage to isolate a sugar -- a ribose -- in gas phase and to characterise a number of its structures. Sugars give rise to enormous biochemical interest given the importance and diversity of the functions they carry out: they act as an energy storage system and serve as fuel for a number of biological systems; they form part of DNA and of ribonucleic acid

In a study of the molecular underpinnings of plants' pest resistance, Rice University biologists have shown that plants both anticipate daytime raids by hungry insects and make sophisticated preparations to fend them off. "When you walk past plants, they don't look like they're doing anything," said Janet Braam, an investigator on the new study, which appears this week in the

Researchers at the University of Georgia have taken a major step in the ongoing effort to find sources of cleaner, renewable energy by mapping the genomes of two originator cells of Miscanthus x giganteus, a large perennial grass with promise as a source of ethanol and bioenergy. Changsoo Kim, a postdoctoral research associate in the UGA Plant Genome Mapping Laboratory, identified a set of approxi
